Effects of Zika Mosquito Control Measures Interventions Targeted to Pregnant Women in 2019, Bueng Kan Province

Abstract

The prospective research was conducted to measure the impacts of strict mosquito control on contracting the Zika Virus and to reduce the density of Aedes aegypti near pregnant women’s homes. Samples were 13 pairs of pregnant women who resided in Bueng Kan Provinc. Chemical residuals in the group of intensive mosquito control were used as the sprayed instrument. Activities were similar for both groups: surveying Aedes aegypti, setting up the mosquito trap, interviewing and getting rid of Aedes aegypti larvae weekly for 5 months. Research findings revealed that 13 pregnant women in the control group had an average age of 25.62 years (S.D.=5.69 years). Majorities reduced the number of mosquitoes by getting rid of wastes from the residential area by 81.08%. Most pregnant women used products such as mosquito spray, mosquito repellant, mosquito repellant lotion, and mosquito nets to reduce the mosquito’s number. Majorities or 79.73% used mosquito nets, and 13 pregnant women in the intervention group had an average age of 23.31 years (S.D.=5.14 years). For the reduction of mosquito numbers, in most samples,78.38% disposed of wastes from the residential areas, and the use of products such as mosquito spray, mosquito repellent, mosquito repellent lotion, and mosquito nets to reduce the number of mosquitoes among the pregnant women. Majorities 83.11% used mosquito nets, and there were no differences in the Mean of Aedes aegypti larvae between the control group and the intervention group, but the Mean of the control group had House Index (HI) reduced by 24.23%, Container Index (CI) at 10.97%, intervention group had House Index (HI) reduced by 20.00%, having statistical significance 0.05. Also, the density of matured mosquitoes, namely, home aedes aegypti and aedes albopictus suggested no differences between both groups, but the control group had a density of aedes aegypti reduction of 5.77%, having a statistical significance of 0.05 as well as detecting of the Zika virus in both human and mosquito carriers. The study results recommended the Health Department divisions and responsible sections survey the area in order to eradicate mosquito breeding sites surrounding the pregnant women’s homes and community, which should reduce CI and HI, which in turn reduce the risk of contracting Zika virus among the pregnant women and community, leading to effective diseases prevention and control.
